For our WOW activity, we made invisible ink hand and footprints. We used warm water and baking soda. We asked the babies if they felt how warm the water was. We asked the babies if the warm water felt nice in between there toes. The baking soda left a weird texture on our sands. We asked the babies how it felt. (Rough, squishy, sandy etc) We then used turmeric and hand sanitizer to Create the ink effect. We asked the babies to smell the turmeric. It created a fun effect.
